"Debates in classrooms can get very heated".
I love when I hear that...to anyones knowledge has debate in the classroom @ CU ever lead to any kind of assault with a deadly weapon? Somehow I doubt it...its thos whole mentality of anti gun types that a firearm somehow turns otherwise normal well adjusted individuals into mass killers waiting for a reason to strike.
In the la-la-land of anti-gun-ville if every gun was destroyed tomorrow there would be no crime, dogs and cats would live side by side and we would all agree to stop eating meat while we are at it.
Good luck with campus carry in Colorado; hopefully after a few years of no blood in the street/classroom Colorado can be called upon as yet another example of why campus carry works.
